下列哪些臨床徵象與低血鈣有關？（選所有適合的）
Which of the following clinical signs are associated with hypocalcemia? (Select all that apply.)
- APositive Trousseau's sign✓ 正解Trousseau 徵象陽性
- BPositive Chvostek's sign✓ 正解Chvostek 徵象陽性
- CMuscle cramps✓ 正解肌肉痙攣
- DHyperactive deep tendon reflexes✓ 正解深層肌腱反射亢進
- EHypoactive bowel sounds腸音減弱
— Explanation · 中文詳解 —
低血鈣導致神經肌肉興奮性增加，出現 Trousseau's 徵象（腕痙攣）、Chvostek's 徵象（顏面神經抽搐）、肌肉痙攣及深部肌腱反射亢進。低血鈣反而會刺激腸蠕動，因此通常會出現腸蠕動音亢進，而非減弱。
Hypocalcemia increases neuromuscular excitability, leading to clinical signs such as positive Trousseau’s and Chvostek’s signs, muscle cramps, and hyperactive deep tendon reflexes. Unlike hypercalcemia, which decreases gut motility, hypocalcemia stimulates intestinal peristalsis, resulting in hyperactive rather than hypoactive bowel sounds.

兩地對於 Trousseau's 和 Chvostek's 的評估訓練皆屬基礎護理評估的一環。
